“…The OM plays an important role in different steps of the calcification process, such as nucleation, orientation, inhibition, crystal nature and growth regulation (Wheeler et al, 1981(Wheeler et al, , 1988Belcher et al, 1996;Falini et al, 1996). However, the literature still presents a confusing picture of the timing of density band formation that impairs optimal use of these environmental archives (Barnes and Lough, 1996;Hernaman et al, 2000). Some of these difficulties arise from our poor knowledge of the basic control mechanism of calcification at the crystal level, and more particularly the relationship between ionic and organic control.…”

SUMMARYIonic and organic parameters of the otolith calcification process in the trout Oncorhynchus mykiss were analysed in plasma and endolymph over the day:night cycle. Plasma pH remained constant and total CO2concentration was significantly lower (by 21%) during the day than at night. Calcifying parameters (total CO2, total calcium concentration) were measured in the proximal and distal endolymphs and were unchanged in the latter during the day:night cycle, but fluctuated in the former. Non-collagenous protein and collagen concentrations in endolymph were higher(1.5- and 10-fold, respectively) during the day than at night. As there was no change in total calcium concentration, we propose that Ca2+increases during the dark period and was maximal by the end of the night when the total CO2 concentration has also increased (by 14%). Measurements of endolymph pH in situ revealed significant differences between samples from proximal and distal endolymph (7.38 and 7.87,respectively), but no variation between values obtained during the day and at night. Thus, the saturation state of aragonite (Sa) in the proximal endolymph should fluctuate around unity during the day:night cycle, and CaCO3precipitation should occur when supersaturation is reached. The electrophoretic pattern of proximal endolymph showed variations in both major and minor components. Immunoblotting of endolymph, using a rabbit antiserum raised against the otolith soluble organic matrix revealed an increase in the expression of two proteins (65 kDa and 75 kDa) during the day period. We propose that organic matrix and calcium carbonate deposition on the otolith vary antiphasically: organic matrix deposition begins by the end of the day period, when the concentration of organic precursors is maximal in the endolymph, whereas CaCO3 precipitation starts once the solubility of CaCO3 is exceeded.

“…Although this does not definitively prove that rings on otoliths are daily, studies of other small-bodied fish have validated daily growth rings (e.g. Iglesias et al 1997, Hernaman et al 2000. Consequently, it was assumed that opaque rings on S. patzneri otoliths represent daily increments.…”

Growth, mortality and density estimates of the blenny Salarias patzneri were used to quantify turnover rates of a small-bodied detritivorous fish. Turnover rates of S. patzneri were then compared with prominent scarids and acanthurids, to assess the relative significance of small detritivores to secondary production on coral reefs. Instantaneous mortality, estimated from growth parameters (L ∞ = 5.10, K = 3.25, t 0 = 0.10), suggests that less than 99% of the S. patzneri population survives for more than 1 yr. Despite their small body size, high mortality rates combined with high densities give S. patzneri high annual biomass turnover rates that are similar to larger-bodied acanthurids and scarids. Dietary analysis determined that all post-settlement S. patzneri, from juveniles to the largest adults, are detritivorous. The high turnover rates and diet of S. patzneri emphasize the importance of small-bodied fish and detritus to coral reef trophodynamics.KEY WORDS: Coral reef trophodynamics · Secondary production · Growth · Mortality · Body size · Turnover rates · Detritivory · BlenniidaeResale or republication not permitted without written consent of the publisher

“…The method employs commercially available osmotic pumps to deliver calcein, which is a fluorescent compound that binds to calcium in biomineralized structures as it is precipitated (e.g., Medeiros-Bergen and Ebert, 1995;Monaghan, 1993;Moran, 2000;Collin and Voltzow, 1998;Hernaman et al, 2000). Using full immersion incubations, calcein has been used to mark bivalves (e.g., Kaehler and McQuaid, 1999;Moran and Marko, 2005;van der Geest et al, 2011) and in laboratory studies regarding foraminiferal calcification Denoyelle et al, 2012;Dissard et al, 2009;Filipsson et al, 2010;Kurtarkar et al, 2015;Nardelli et al, 2014).…”

Abstract. Insights into oceanographic environmental conditions such as paleoproductivity, deep-water temperatures, salinity, ice volumes, and nutrient cycling have all been obtained from geochemical analyses of biomineralized carbonate of marine organisms. However, we cannot fully understand geochemical proxy incorporation and the fidelity of such in species until we better understand fundamental aspects of their ecology such as where and when these (micro)organisms calcify. Here, we present an innovative method using osmotic pumps and the fluorescent marker calcein to help identify where and when calcareous meiofauna calcify in situ. Method development initially involved juvenile quahogs (Mercenaria mercenaria); subsequent method refinement involved a neritic benthic foraminiferal community. Future applications of this method will allow determining the in situ growth rate in calcareous organisms and provide insights about microhabitats where paleoceanographically relevant benthic foraminifera actually calcify.
